Is this problem only on google chrome?
If its working on flash player when you run (ctr+enter), and works on other browsers. try reinstalling the flash player.
its not you... it's chrome.
i have the same thing... it happens on ALL flash media viewed with chrome (on Mac for me)
there are some bugs posted about it on the google forums.
adobe tells me : Your Google Chrome browser already includes the latest Adobe® Flash® Player built-in...
I just checked. it is very annoying.
